Molded Case Circuit Breakers (MCCBs)

Molded Case Circuit Breakers (MCCBs) are essential devices used to protect electrical circuits from overloads, short circuits, and ground faults. They are widely used in industrial, commercial, and residential applications where current ratings range from low to medium levels.

MCCBs are compact, enclosed devices that integrate thermal-magnetic or electronic trip mechanisms for accurate protection. Their molded outer shell provides insulation and protection, making them safe and reliable for low-voltage power distribution systems.

Benefits With Our MCCBs

Cost-effective, compact, and dependable protection for a wide range of circuits.

  • Thermal-magnetic and electronic trip options available
  • Compact design suitable for panel integration
  • Adjustable trip settings for customized protection

Our MCCBs are built to meet international standards such as IEC 60947-2 and are available in current ratings up to 1600A. They are ideal for feeder protection, motor protection, and as a reliable backup to electronic protection devices. These breakers offer high performance and minimal maintenance, making them an efficient choice for modern electrical systems.

Most Common Questions

What makes MCCBs different from other types of circuit breakers? MCCBs are designed for low-voltage applications and offer adjustable protection settings, making them more versatile than Miniature Circuit Breakers (MCBs). They are ideal for circuits where moderate to high currents are expected.

MCCBs are widely used in low-voltage distribution networks for protecting circuits, motors, and other electrical equipment from overloads, short circuits, and ground faults. They are commonly found in industrial control panels, commercial installations, and residential distribution boards.
MCCBs are designed for higher current ratings (up to 1600A or more) and offer adjustable trip settings, whereas MCBs (Miniature Circuit Breakers) are suitable for lower currents (typically up to 100A) with fixed trip characteristics. MCCBs are better suited for industrial and heavy-duty applications.
MCCBs are available in current ratings from around 15A up to 1600A or more, depending on the model and manufacturer. This wide range makes them ideal for protecting various types of loads in industrial and commercial systems.
MCCBs should be visually inspected and tested periodically, typically every 6–12 months depending on the environment and usage. Key maintenance tasks include verifying mechanical operation, checking terminals, and testing trip mechanisms to ensure reliable protection.
